Just like with my '94 Cobra's JLT Performance cold-air kit, it looked as if the throttle body inlet hose would be a struggle, but thanks to the hose's construction it took little effort to get it installed.

The business end of JLT's cold air is the billet mass airflow housing. A simple click is all that's needed to finish up the cold air kit's installation.

Wow-now that's what I'm talking about. The Three-Valve looks great back together. Now all Matt has to do is button up the exhaust and we're ready to light this candle.

Matt positions the driver-side header in place without opposition. The passenger-side header was a little more stubborn. If you choose to add long-tube headers to your S197, you may have to loosen the engine mounts and jack up the engine to gain sufficient clearance.

OK, so Matt added the 5 quarts of Roush Performance oil to the Three-Valve in preparation for startup. We fired up the engine, but something didn't sound right. The valvetrain had a subtle, yet noticeable clatter to it, like a cammed-up 5.0. We shut off the engine to check things out; then we noticed all the Roush Performance oil on the shop floor-all 5 quarts of it! Apparently, we neglected to transfer these pipe fittings from the original heads to the Blow-By examples, and that's where the oil escaped. We were able to install the fittings to the heads with them on the engine, thankfully, and our valvetrain clatter was non-existent. These fittings maintain oil pressure within the head, and as we found out, also keep oil in the engine. We learned a lesson the hard way so you don't have to.
